Robots and artificially intelligent devices will take over many jobs now done by people, and experts are divided as to whether their spread will do human society more good than harm. The Pew Research Center said experts see a growing role for self-driving cars, delivery drones, robotic workers, smartphone-based assistants and even algorithmic journalism by 2025. Lee Rainie, director of the Pew Research Internet Project, said experts see the accelerating displacement of work that can be done more efficiently and cost-effectively by robots. Automation is (the Harry Potter villain) Voldemort: the terrifying force nobody is willing to name, said Jerry Michalski, founder of Relationship Economy eXpedition, a think tank of corporate executives.
